What is a common symptom of heat stroke?

In the context of heat stroke, a common symptom is severe headache. This condition occurs when the body overheats, typically as a result of prolonged exposure to or physical exertion in high temperatures. During heat stroke, the body's thermoregulatory mechanisms fail, leading to hyperthermia. A severe headache can develop as a result of the body's stress response to rising body temperature and dehydration.

While other symptoms are associated with heat stroke, such as confusion or altered mental state, dry skin is specifically relevant here because, during heat stroke, the skin may actually be hot and dry due to failure of the body to sweat effectively. Additionally, uncontrollable shivering is indicative of hypothermia rather than heat stroke, and rapid breathing can occur in various conditions, but it doesn't specifically indicate heat stroke as clearly as a severe headache does.
